Why does my 555 debouncing circuit not working?

Help! I just followed the schematic diagram given here, http://www.555-timer-circuits.com/switch-debounce.html but the simulator says there is an error.

Hello,

Try changing the interactive simulation settings under the Simulate tab. GO to analysis options>>use custom settings and in Customize..., change the RSHUNT value to 1e+008 ohms.

Kind Regards,
